Description

Technical Field

[0001] This utility model relates to the field of walkie-talkie antenna technology, and more specifically to a walkie-talkie antenna protection structure. Background Technology

[0002] A walkie-talkie is a portable wireless communication device, mainly used for two-way voice communication over short distances. It includes, but is not limited to, a transmitter, receiver, speaker, microphone, and antenna. The antenna is a very important part, and its main function is to send and receive radio wave signals. The antennas for existing walkie-talkies, as shown in "Application No.: CN202422561070.6, Ultra-low Cost High Performance Walkie-Talkie Antenna" and "Application No.: CN201320744346.3, Antenna for Walkie-Talkies", use a threaded structure for disassembly and assembly. Because walkie-talkies may be subjected to vibration or impact during use, the threaded connection may easily loosen and require repeated tightening, which has the disadvantage of accelerating wear; and when loose, it also has the disadvantage of poor waterproof and dustproof functions. Utility Model Content

[0003] The purpose of this utility model is to provide a walkie-talkie antenna protection structure in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a walkie-talkie antenna protection structure, including a body and an antenna threadedly connected to it; A clamping device is provided between the body and the antenna; The clamping device includes a convex ring fixed to the outside of the antenna, an upper washer that fits against the top of the convex ring, an L-shaped ring sleeve fitted outside the antenna, an annular groove at the top of the body, and a lower washer that fits against the bottom of the annular groove. The upper washer is attached to the inner side of the L-shaped ring sleeve. The L-shaped ring sleeve extends into the ring groove and is threaded to connect with the top of the lower washer. The threads between the L-shaped ring sleeve and the ring groove rotate in the opposite direction to the threads between the body and the antenna.

[0005] In a preferred embodiment of this invention, the upper and lower washers are made of rubber.

[0006] As a preferred embodiment of this utility model, at least one set of anti-loosening devices is provided between the body and the L-shaped ring.

[0007] As a preferred embodiment of this utility model, the anti-loosening device is provided in multiple sets and is evenly distributed outside the L-shaped ring.

[0008] As a preferred technical solution of this utility model, the anti-loosening device includes an inclined rod fixed to the outside of the L-shaped ring, a rod cavity provided on the end of the inclined rod, a threaded rod threadedly connected in the rod cavity, an outer rod fixed to the outside of the threaded rod, a gripping ring fixed to the outside of the outer rod, and a slot provided on the top of the machine body. A pressure pad is fixedly fitted inside the slot; the threaded rod rotates in the rod cavity to drive the outer rod to extend into the slot until it is in contact with the pressure pad.

[0009] As a preferred embodiment of this utility model, the compression pad is made of rubber.

[0010] The beneficial effects of this utility model are as follows: When the L-shaped ring is connected to the outside of the antenna, it can improve the support strength of the antenna connection position. The compression of the L-shaped ring on the antenna can improve its position stability, thereby reducing the possibility of the antenna loosening. The upper and lower washers can further improve the waterproof and dustproof sealing effect. The thread direction of the L-shaped ring connecting to the ring groove is opposite to the thread direction of the connection between the body and the antenna. In this way, when the antenna generates rotational loosening force, the L-shaped ring can provide a relatively blocking and suppressing force, improving structural stability. The anti-loosening device is used to improve the stability of the L-shaped ring fixing position, thereby improving the anti-loosening effect during antenna use. Attached Figure Description

[0013] like Figure 1 As shown in the figure, this embodiment proposes a walkie-talkie antenna protection structure, including a body 1 and an antenna 2 threadedly connected to it, which provides the effect of easy disassembly and replacement; A clamping device 3 is provided between the body 1 and the antenna 2 to improve the stability of the antenna 2 installation position; Specifically: The clamping device 3 includes a convex ring 31 fixed to the outside of the antenna 2, an upper washer 32 that fits against the top of the convex ring 31, an L-shaped ring sleeve 33 sleeved on the outside of the antenna 2, an annular groove 34 located at the top of the body 1, and a lower washer 35 that fits against the bottom of the annular groove 34. The inner side of the L-shaped sleeve 33 is fitted with the upper washer 32. The L-shaped sleeve 33 extends into the inner thread of the ring groove 34 and is threaded to fit the top of the lower washer 35. The threads between the L-shaped sleeve 33 and the ring groove 34 rotate in the opposite direction to the threads between the body 1 and the antenna 2. A protruding ring 31 is pre-fixed on the outside of the antenna 2. The outer cladding of the antenna 2 is generally made of plastic or rubber. The protruding ring 31 can be made in one piece or directly fixed to the outside of the antenna 2 by adhesive bonding. A ring groove 34 is opened on the outer periphery of the antenna 2 and the top of the body 1. The lower washer 35 is attached and fixed in the ring groove 34 by adhesive bonding (epoxy resin glue or silicone glue). The upper washer 32 is attached and fixed to the top of the protruding ring 31, and the attachment position is fixed by adhesive bonding (epoxy resin glue or silicone glue). A thread is provided on the lower part of the inner side of the L-shaped ring 33 to connect with the ring groove 34. The structure of the L-shaped ring 33 is shown in the figure. It is composed of two ring plates, an upper ring plate and a lower ring plate. The bottom end of the upper ring plate is attached to the upper washer 32, and the bottom end of the lower ring plate is attached to the lower washer 35. Together they fit around the antenna 2. When the L-shaped ring 33 is connected to the outside of the antenna 2, it can improve the support strength of the antenna 2 connection position. The compression of the L-shaped ring 33 on the antenna 2 can improve its position stability, thereby reducing the possibility of the antenna 2 loosening. The upper washer 32 and the lower washer 35 can further improve the waterproof and dustproof sealing effect. The thread direction of the L-shaped ring 33 connected to the ring groove 34 is opposite to the thread direction of the connection between the body 1 and the antenna 2 (that is, when the L-shaped ring 33 is fixed by clockwise rotation, the antenna 2 is fixed by counterclockwise rotation). In this way, when the antenna 2 generates rotational loosening force, the L-shaped ring 33 can provide a relatively blocking and suppressing force, thereby improving the structural stability.

[0014] The upper washer 32 and the lower washer 35 are made of rubber, which provides good sealing performance and strong durability under deformation compression. Example 2:

[0015] like Figure 1 As shown, the difference between it and Embodiment 1 is that it also includes at least one set of anti-loosening devices 4 between the body 1 and the L-shaped ring 33, which is used to improve the stability of the fixed position of the L-shaped ring 33 and improve the anti-loosening effect when the antenna is used. Among them, the anti-loosening device 4 is provided in multiple sets and is evenly distributed outside the L-shaped ring 33; such as Figure 1 As shown, two sets are symmetrically arranged on the left and right sides of the L-shaped ring 33 to further improve the anti-loosening effect when the antenna is in use; Specifically: the anti-loosening device 4 includes an inclined rod 41 fixed to the outside of the L-shaped ring 33, a rod cavity 42 provided on the end of the inclined rod 41, a threaded rod 43 threadedly connected to the rod cavity 42, an outer rod 44 fixed to the outside of the threaded rod 43, a gripping ring 45 fixed to the outside of the outer rod 44, and a slot 46 provided at the top of the machine body 1. A pressure pad is fixedly fitted inside the slot 46; the threaded rod 43 rotates threadedly inside the rod cavity 42 to drive the outer rod 44 to extend toward the slot 46 and until it is fitted with the pressure pad. As shown in the figure, one end of the inclined rod 41 is fixed to the outside of the L-shaped ring 33, and the inclined rod 41 is inclined downward. A rod cavity 42 is recessed inward at the center of the other end of the inclined rod 41. One end of the threaded rod 43 is threaded into the rod cavity 42 and moves in and out. One end of the outer rod 44 is fixed at the other end of the threaded rod 43. A fixing ring 45 is sleeved around the outer rod 44 to serve as the force application position for rotating the threaded rod 43. Anti-slip texture can be provided on the outside of the ring 45 to improve stability during rotation. The lower end of the outer rod 44 extends towards the groove 46 through the rotation of the threaded rod 43 until it extends into the groove 46 and fits and is fixed to the pressure pad. This can further improve the stability of the L-shaped ring 33. Furthermore, the anti-loosening device 4 can also be used as a component to apply force to the rotating L-shaped ring 33, so as to facilitate operation and rotation, and the structure has high utilization.

[0016] The compression pad is made of rubber, which is durable and provides a deformation compression effect.
